Since I haven't been fortunate to have the experience of having children of my own to sing a lullaby to, I guess this is from the perspective of a guy who is singing his wife to sleep. This took shape after starting with the title, the motivation for which was simply to have a song with the word 'lullaby' in it. At the time I think what I had in mind was to do the same for all the other similar words like rag, dirge, reel, etc., just as a songwriting practice exercise. Lenore played a sweet flute on this one. I included it because it fit the album theme, particularly when you consider the fact that it's great sleeping on a boat because the rocking literally lulls you to sleep.
